What kind of answer was that?
"Don't tell me there are flaws in this array formation?" asked Lu Wuchang nervously.
"It's not that bad."
Pu Mingyue chuckled. "What I mean is that the Nine Lotus Eight Trigrams Array is just an array formation. Since it's an array formation, it can be broken. As long as someone can unlock it, they can freely enter and exit the valley.
"Of course, it won't be easy to do that. This formation has been extremely famous since a thousand years ago. Even if an array formation grandmaster were to come, he wouldn't be able to break it easily.
"Firstly, I've fused it with the vital energy of the valley. Forcefully breaking the array formation will target the entire valley, and even the surrounding mountains. To break it, one has to succeed in one go. Even a first-grade martial artist cannot do this.
